Same Site Typo?

Question

In question 5 you ask if https://project1.github.com and https://project2.github.com are same-site.

I assume you meant for the answer to be they are not same site, because github is in the suffix list.

However only github.io is in the suffix list, not github.com. (https://publicsuffix.org/list/public_suffix_list.dat)

Answer 1

I'm not sure what your question is; the task seems correctly phrased to me.

You have all the information to answer if the statement in correct or not.
